 Release History
 ===============
 
+0.1.0 (2024-04-09)
+------------------
+
+- fling.py, chain.py, guard.py, admin-guide.rst:
+
+  Add --debug argument and use args.debug for all debugging related
+  output, and be consistent in use of args.verbose for verbose output
+  (e.g., progress messages).
+
+- chain.py:
+
+  + Log when a CA certificate is not in any of Apple, Google Chrome,
+    Microsoft, Mozilla root stores.
+  + Log when 0 intermediates found for a CA certificate.
+
+- chain.py:
+
+  Add message when all certificate chains were downloaded
+  successfully.
+
+- chain.py:
+
+  + Display PAN-OS certificates not in CCADB and consider them
+    invalid, because we will not find intermediate certificate chains
+    for these.
+  + Output invalid PAN-OS certificate messages to stderr.
+  + Display total invalid PAN-OS certificates found.
+
+- chain.py: Fix invalid path in error.
+
+- chain.py: Print download error to stderr.
+
+- chain.py: Also retry on status code 502, 504.
+
+- chain.py: Improve some messages.
+
+- chain.py:
+
+  Since we don't use xapi.export_result 'file', check 'content'
+  instead.  There is currently an issue in pan.xapi export() where
+  filename can be None.  Fixes a bug where certificate names with
+  parentheses were not saved to the archive.
+
+- chain.py: exit with status 2 when there are download failures.
+
+- chain.py:
+
+  + Fix missing value for format string.
+  + Change message to Error.
+
+- Documentation improvements and fixes.
